Final word on this if you where reading.
China was too expensive, the 298mm mould they had was only 1050 long so the final price from them came in at :
Tube: USD428.05/pcs
Mould fee:USD440.52
Shipping:USD205.58
Amount:USD1074.15
I also contacted protostar and was told they do not ship lengths over 36" off shore anymore
